Herein, what is the heat of formation of benzene?

The standard enthalpy of formationofbenzene,C6H6, is+49.2KJ/mole.

Secondly, at what temperature is benzene a liquid and a gas? Benzene boiling point at atmospheric pressureis80 °C (176°F), and hence, benzene mustbepressurized to remain liquid at highertemperaturesthan that.

Similarly, how do I calculate specific heat?

Enter the necessary data and then click on the activetextabove for the quantity you wish to calculate.

  1. For a mass m = gm = kg.
  2. with specific heat c = cal/gm°C = joule/gm°C,
  3. initial temperature Ti = °C = K = °F.
  4. and final temperature Tf = °C = K = °F,
  5. Q = calories = kcal = x 10^ calories.
  6. Q = joules = x 10^ joules.

Is benzene solid or liquid?

Benzene is the name of an aromatichydrocarbon,C6H6. In liquid form,benzeneis clear, colorless and flammable. At roomtemperature, liquidbenzene evaporates easily into the air,and can dissolve inwater. In the environment, benzene may bepresent in air,water, and soil.

Why is the enthalpy of formation of oxygen 0?

The enthalpy of formation for an element initselemental state will always be 0 because it takes noenergyto form a naturally-occurring compound. So in thiscase,ΔHrxn,H2O=ΔHf,H2O . When a substance is formedfrom themost stable form of its elements, a change inenthalpy takesplace.

How do you calculate change in enthalpy?

Use the formula ∆H = m x s x ∆Ttosolve.
Once you have m, the mass of your reactants, s,thespecific heat of your product, and ∆T, thetemperaturechange from your reaction, you are prepared tofind theenthalpy of reaction. Simply plug your values intotheformula ∆H = m x s x ∆T and multiplytosolve.

Why is specific heat important?

A high specific heat of a substance means thatalarge amount of heat is required to raise the temperatureofthe substance. Water covers around 70% of the Earth's surfaceandits high specific heat plays a very important roleasit is able to absorb a lot of heat without asignificantrise in the temperature.
